TECHNICAL DATA CONSTANT CURRENT LINEAR LED DRIVER IK402U DESCRIPTION IK402U is a high-stable current source IC designed to be used as a constant currentLED driver. Application of a constant current source provides continuous brightness of LED light and long LED life time. Moreover, a constant current source provides an over-temperature protection to LED. SOT-23-6 FEATURE High-stability output current Low dropout voltage Negative thermal coefficient of output current Small overall dimensions, possible chip mount in a single package with LED Low cost, no external elements, simple use LED drive current of 22 mA Supply voltage up to 42 V Easy paralleling of drivers to increase current Low voltage overhead of 1.2 V High current accuracy at supply voltage variation No EMI ESD Rating: Human Body Model 2000V Reduced output current at higher temperatures negative thermal coefficient of - 0.1 %/K APPLICATION Channel letters for advertising, LED strips for decorative lighting Aircraft, train, ship illumination Retrofits for general lighting, white goods like refrigerator lighting Medical lighting Automotive applications like CHMSL and rear combination lights IK402U MAXIMUM RATINGS Parameter Symbol Value Unit Supply voltage V 42 V S Output voltage V 18.6 V OUT Reverse voltage between all terminals V 0.5 V R Junction Temperature Tj 40+150 C P = (V V ) I is determined by theconditionTj 150C max S OUT OUT ELECTRICAL CHARACTERISTICS ( Tj= +25C, unless otherwise noted) Parameter Symbol Condition Min Typ Max Unit Collector-emitter V I = 1 mA, I = 0 60 V BR(CEO) C B breakdown voltage Supply current I V = 10 V 340 440 540 A S S Output current I V = 10 V, V = 8.6 V 19 22 24 mA OUT S OUT Internal resistor R I = 20 mA 35 41 45 Ohm INT Rint Voltage drop (V V ) V I = 20 mA 0.7 0.82 0.9 V S E drop C DC current gain h I = 50 mA, V = 1 V 50 100 400 FE C CE DC Characteristics with stabilized LED load Lowest sufficient battery V I > 18mA 1.2 V Smin OUT voltage overhead V = 10 V, S Output current change I /I 0.1 %/ C OUT OUT versus T T = (45 C+85 C) A A Output current change V = 10 V 1.0 %/V I /I OUT OUT S versus V S 2 Aug 2019, Rev. 04
